A small fraction of people, however, cannot recognize faces—even the faces of their parents, spouses, and children. Prosopagnosia, as this condition is known, can affect people from birth or be triggered later in life by injuries to the brain. It strikes an estimated 2 percent of Americans and is often accompanied by other types of recognition impairments, including difficulty recognizing places and objects, such as cars.

The human brain consists of about one billion neurons. Each neuron forms about 1,000 connections to other neurons, amounting to more than a trillion connections. If each neuron could only help store a single memory, running out of space would be a problem.

Randy Gallistel and Adam King in their book Memory and the Computational Brain: Why Cognitive Science Will Transform Neuroscience, claim that addressable memory architecture is necessary to explain complex animal behaviour such as food caching by Scrub Jays or even the human capacity to recollect and reconsider prior beliefs.

Their view is contrasted with non-addressable architecture in contemporary neuroscience. Traditional neural networks suppose that computations in neural tissue are implemented by relaying action potentials between neurons. Gallistel and King argue that the implementation must be sought elsewhere. They offer two neurobiological suggestions of where to look, 1) subcellular, e.g. dendritic spines and 2) molecular, something like re-writable DNA & RNA. Philosophy of Memory

A new study suggests that, like everyone else, I recorded these emotional memories independently of the factual aspects of the day.

There’s nothing like a good nap. It can refresh your mood—and possibly your memory. Because a new study in the journal Science shows that a quick snooze after a mental workout helps to consolidate learning. And that sounds heard during sleep can trigger associations that sharpen memory even more.

Tsien, based at Princeton University in New Jersey at the time, named his creation Doogie after the teenage genius in the television programme Doogie Howser, MD. The work was one of the earliest examples of neuroscientists using genetic engineering to generate cognitively enhanced animals in a bid to understand memory and learning.

I first saw Price last May in a YouTube clip of her on 20/20. Diane Sawyer asks Price, an avid television viewer, to identify certain significant dates in broadcast history. When did CBS air the "Who shot JR?" episode of Dallas? When was All in the Family's baby episode shown? And so on. Price nails every question. She not only gives the date for the final episode of MASH but describes the weather that day.

Emerging technologies raise the possibility that we may be able to treat trauma victims by pharmaceutically dampening factual or emotional aspects of their memories. Such technologies raise a panoply of legal and ethical issues. While many of these issues remain off in the distance, some have already arisen.

In this brief commentary for the journal Neuroethics, I discuss a real-life case of memory erasure. The case reveals why the contours of our freedom of memory -- our limited bundle of rights to control our memories and be free of outside control -- already merit some attention.

The term 'Rashomon effect' is often used by psychologists in situations where observers give different accounts of the same event,and describes the effect of subjective perceptions on recollection. The phenomenon is named after a 1950 film by the great Japanese director Akira Kurosawa.

Researchers in Brooklyn have recently accomplished comparable feats, with a single dose of an experimental drug delivered to areas of the brain critical for holding specific types of memory, like emotional associations, spatial knowledge or motor skills.

Because image-enhancing technology is readily availabl e, people are frequently exposed to doctored images. However, i n prior research on how adults can be led to report false childhood memories, subjects have typical ly been exposed to personal ized and detailed narratives describing false events. Instead, we exposed 20 subjects to a false childhood event via a fake photograph and imagery instructions.

Given only a small dose of oxytocin, individuals in a recent study found that their memory significantly improved. Not for historical dates, strings of digits, or bars of music, but for something much more significant: each other. (Seed)

If a similar phenomenon occurs in humans, the effectiveness of one's memory during adolescence, particularly in those with defective cell signaling mechanisms that control memory, can be influenced by environmental stimulation experienced by one's mother during her youth. (Deric Bownds' MindBlog)
